FIELD OF THE INVENTION

The present invention generally relates to computer-based virtualuniverses, and more specifically, to a method and system for virtualenvironment preservation based on automated item reduction.

BACKGROUND

Virtual universes (VUs) are rapidly becoming a popular part of today'sculture. A VU is a computer-based simulated environment. Many VUs arerepresented using 3-D graphics and landscapes, and are populated by manythousands of users, known as “residents”. Often, the VU resembles thereal world such as in terms of physics, places, and landscapes.

VUs are also known as metaverses and “3D Internet.” Some example VUsinclude: SECOND LIFE™, ENTROPIA UNIVERSE®, THE SIMS ONLINE™ andTHERE™^(_) as well as massively multiplayer online games such asEVERQUEST®, ULTIMA ONLINE™, LINEAGE® and WORLD OF WARCRAFT®.

A VU is intended for its residents to traverse, inhabit, and interactthrough the use of avatars. In operation, user(s) control the avatar(s).An avatar is a graphical representation selected by the user, oftentaking the form of a cartoon-like human or other figure. The user'saccount, upon which the user can build an avatar, is tied to aninventory of assets the user owns, such as, for example, clothing,weapons, artwork, furniture, virtual pets, houses, virtual vehicles, andlandmarks, amongst other assets. A region is a virtual area of landwithin the VU, typically residing on a server's central processing unit(CPU). A user context includes a very broad range of attributes thatdescribe the user and which are relevant to their behavioral, search andother informational needs.

The data representation of an object or item in the VU is stored asinformation, e.g., as data or metadata. The object may be created by anobject creator, e.g., a VU manager, a user, etc. In some virtualuniverses, larger objects are constructed of smaller objects, termed“prims” for primitive objects. These “prims” usually include boxes,prisms, spheres, cylinders, tori, tubes and/or rings. The “prims” may berearranged, resized, rotated, twisted, tapered, dimpled and linked tocreate larger composite objects. The creator of such an object may thenmap a texture or multiple textures to the object. Texture mapping is amethod of adding detail, surface texture, or color to acomputer-generated graphic or 3D model. When the object is to berendered, this information is transmitted from the VU server to theclient.

An inventory of assets comprises objects associated with the user'sindividual avatar or placed by the user on virtual land they own or onpublic land. Such objects may have been created by the user from prims,purchased, or obtained for free. Examples of objects include clothing,weapons, artwork, furniture, virtual pets, houses, virtual vehicles, andlandmarks, amongst other objects. Assets, avatar(s), the environment,and everything else visually represented in the VU each compriseuniversally unique identifiers (UUIDs) (tied to geometric datadistributed to user(s) as textual coordinates), textures (distributed touser(s) as graphics files), and effects data (rendered by the user'sclient according to the user's preference(s) and user's devicecapabilities).

DETAILED DESCRIPTION OF THE INVENTION

The present invention generally relates to computer-based virtualuniverses (VUs), and more specifically, to a method and system forvirtual environment preservation based on automated item reduction. Forexample, the present invention provides automatic, criteria-basedmethods for asset reduction. In embodiments, the methods for assetreduction may include removing or deleting the assets, changing theassets' graphical characteristics to reduce computational load, orarchiving the assets. Additionally, specific identified criteria,including combinations of real world and virtual world criteria, may beused as triggers for asset reduction.

The number of available resources such as landmarks, events, retailstores, services, and other avatars (who might serve business andpersonal needs) is proliferating in VUs. Due to this proliferation,users' avatars accumulate personal inventory items and assets that areplaced on the landscape by receiving them for free, purchasing them, orconstructing them from prims. Over time, however, while VU users'interests and needs may change, and certain assets used directly bytheir avatars, such as clothing, or assets that are placed on virtualprivate or public land are, e.g., no longer relevant or useful to theneeds of residents, companies, or other businesses, VU users continue tomaintain these, e.g., irrelevant or less useful assets.

As a result, VUs are becoming overwhelmed by assets (e.g., asset orinventory clutter) in the form of avatar personal inventory items andobjects placed on virtual land. For this reason, residents may havedifficulty finding relevant assets. Additionally, the overallperformance of the VU may be negatively impacted.

Also, asset clutter affects individual users by increasing thedifficulty for them to locate relevant assets. Additionally, due toasset clutter, the demands on the VU infrastructure may be increased.Asset clutter affects the overall performance of virtual universes,because of the computationally intensive nature of rendering theseassets. As an example of the impact of such computing resourcelimitations, a large enterprise recently sent out an urgent message toemployees with avatars and objects on enterprise owned islands in a VU,urging them to reduce their prims as soon as possible.

In addition, there may be computing resource limitations associatedwith, for example, a VU land of a specific size, which may preclude useof the VU land for special events, involving, e.g., a temporary influxof additional avatars and their associated personal inventory items.That is, if a VU land is to be used for a special event, and plannersanticipate that the special event will create an influx of VU residentsto the VU land, this influx may cause a prim limit to be exceeded.

Within VUs, manual methods are known for reducing asset clutter forinventory management. Recommended asset clutter solutions include anumber of suggestions for inventory management, including:

-   1. Organize inventory contents regularly. Do not keep two copies of    the same, replicable item in inventory since they may be copied    again from the public library object collection if needed.-   2. Use subfolders to organize inventory contents.-   3. Do not carry objects not likely to be used in the near future.    Use the trash function to delete everything you probably won't use.    Empty the trash at the conclusion of every SL session. The items in    the trash can take up as much space as they did in their original    folders.-   4. Make a backup copy of the primary avatar's Inventory. Put it in a    storage prim outside the primary avatar's inventory, or copy folders    and items into an alternate avatar's inventory.-   5. The debug menu will provide a list of everything identified by    Second Life which is considered “clothing” (or whatever other    category is selected) and can be removed to trash directly from the    list.-   6. Sort all inventory folders and items by date of acquisition and    decide to store older creations outside of active inventory.-   7. Create a storage prim to remove items in certain categories from    active inventory. Items can be copied back into the resident's    inventory when needed. Stores such as THiNC    (http://thincsl.com/category/products/inventory-box-organizer/)    provide specialized inventory management aids including specialized    security boxes for textures and for photos.-   8. Storage prims can be place on a user's rented or owned property    and also be copied to a friend's inventory in case the primary    inventory gets corrupted.-   9. Obtain a second user account and create an alternate avatar. Use    the Search function to directly transfer some inventory items from    the primary avatar to the alternate.

While these asset management techniques describe manual methods toenable residents to delete or archive categories of assets, they fail toaddress a number of situational criteria for automatic asset reductionthat span a number of the asset categories addressed by these previouslydisclosed manual methods. These manual methods also require significanteffort by users who do not perform such cleanups often.

By implementing the present invention, VU residents may more easilylocate assets due to the reduction of asset clutter. Additionally, VUresidents will experience improved overall performance in the VUincluding reduced time to load their inventory. VU service providerswill also need fewer computing resources to provide a responsiveimmersive environment and will have the flexibility to host specialevents without concerns about performance issues or denial of access tospecific virtual lands because of prim overload. Further, throughreduced asset clutter, increased performance and enhanced relevance,businesses may be able to satisfy and service customer needs (and createa good impression).

The computing device 14 includes a processor 20, a memory 22A, aninput/output (I/O) interface 24, and a bus 26. The memory 22A caninclude local memory employed during actual execution of program code,bulk storage, and cache memories which provide temporary storage of atleast some program code in order to reduce the number of times code mustbe retrieved from bulk storage during execution.

Further, the computing device 14 is in communication with an externalI/O device/resource 28. The external I/O device/resource 28 may bekeyboards, displays, pointing devices, etc. The I/O device 28 caninteract with the computing device 14 or any device that enables thecomputing device 14 to communicate with one or more other computingdevices using any type of communications link.

Asset Reduction

The present invention provides automatic, criteria-based methods forasset reduction. The inventive methods provide several asset reductionoptions, including: permanent or semi-permanent reduction (deletion) ofidentified assets, changing graphical characteristics of identifiedassets and temporary reduction of assets via archival storage.

According to an aspect of the invention, the asset deletion tool 30 mayautomatically permanently or semi-permanently reduce (e.g., delete)identified assets of a user using a “recycle bin/trash” in a VU. In aVU, this may be accomplished, for example, by teleporting an item to the“trash dump” or “storage closet” region, to which, for example, anavatar may visit for a period of time after deleting or reducinginventory. Additionally, in embodiments, the asset deletion tool 30 maymove these identified assets to a recycle/trash bin on the end user'scomputer. Additionally, scripts (e.g., programs) may be associated withobjects. In embodiments, these associated scripts may be separated fromthe objects and handled separately.

According to a further aspect of the invention, with a second assetreduction method, the asset graphical characteristics alteration tool 35may alter the graphical characteristics of identified assets, such as,for example, texture mapping detail or color, amongst other graphicalcharacteristics, to reduce the computational load on the VU. Forexample, the asset graphical characteristics alteration tool 35 mayreduce the number of facets that compose an object to create alower-resolution version (that, for example, requires less computationalload to render in the VU). Additionally, for example, the assetgraphical characteristics alteration tool 35 may eliminate textures tocreate monochrome objects. In embodiments, the asset graphicalcharacteristics alteration tool 35 may perform some of these reductionsgradually so that users have visual indication of their lesser usedobjects. For example, the asset graphical characteristics alterationtool 35 may control an object to flash, blink or fade for a time beforethe asset graphical characteristics alteration tool 35 alters the objectinto, e.g., a low-resolution mode.

According to a further aspect of the invention, with a third assetreduction method, the asset archival storage tool 40 may reduce assetsvia moving the assets to a secondary archival storage, e.g., thearchival storage system 22C. The off-load (or moving) of assets to thissecondary archival storage system 22C reduces the demand on a VU mainstorage and/or a database, e.g., storage system 22B. In embodiments, theasset archival storage tool 40 may provide a user an option for lateraccess and restoration of the temporarily reduced asset. Additionally,in embodiments, this secondary archival storage system 22C, e.g., adatabase, may be based on some cheaper and/or slower technology.

VU Triggers For Asset Reduction

According to a further aspect of the invention, a VU monitoring tool 45may monitor specific identified criteria including, for example, acombination of real world and VU criteria. Additionally, in embodiments,the VU monitoring tool 45 may use the specific identified criteria astriggers for asset reduction. The first four criteria involve thedetermination of relevance in four dimensions in the VU: 1) relevance tolandscape; 2) relevance to collaboration with other VU residents; 3)relevance to user context; and 4) relevance to mode of transportation.In each of the respective dimensions, the method used to determinerelevance will vary by embodiment, but all potential methods used withthe inventive system should have the aim of associating VU items with VUresidents.

1. Reduction by Relevance to Landscape

In embodiments, the VU monitoring tool 45 may determine if a region hasnot been visited by a specific resident within a preset duration. If theVU monitoring tool 45 determines that the specific resident has not beento that region within the preset duration, the VU monitoring tool 45 maydetermine that an item is relevant or related to that particular land orregion of the VU. Additionally, the VU monitoring tool 45 may direct thereduction of the relevant asset or item. For example, the VU monitoringtool 45 may direct the asset archival storage tool 40 to move therelevant inventory items for that resident to the archival storagesystem 22C.

In embodiments, the VU monitoring tool 45 may determine relevance ofitems to landscape by associating VU items with residents and regions.For example, with an exemplary method, the VU monitoring tool 45 maydetermine that an item is relevant or related to a particular land orregion if the user placed the object and left the item in the particularland or region, and the user is the only resident who has used that itemon that land. With another exemplary method, the VU monitoring tool 45may determine that an item is relevant to a particular land or region ifthe item was purchased or acquired for free on a previous visit to thatland or region (or elsewhere) and the content of the inventory item isspecific to that land or region (e.g., tourist map of that land orregion).

In an exemplary method, the VU monitoring tool 45 may monitor regionvisitation by resident and determine whether the region has been visitedby the resident within a predefined time period. In embodiments, thepredefined time period may be configurable by, e.g., the user, a VUservice provider or an asset reduction service provider. With anexemplary method, the VU monitoring tool 45 may keep track of regionnames in a database, e.g., storage system 22B, with a visit counter thatspecifies, for example, the number of times or hours a user spends inthat region.

If the VU monitoring tool 45 determines that a resident has not visitedthe region within the predefined time period, the VU monitoring tool 45may determine items deemed to be relevant to this region. With anexemplary method for determining items relevant to a region, the VUmonitoring tool 45 may track in a database, e.g., storage system 22B,records that contain, for example, the location, the item, and a time ofuse or withdrawal of the item from inventory, amongst other information.Each item can have an identification (ID), e.g., UUID, and the recordmay specify the items location and a VU user's visits within a radius ofthe item.

FIG. 2 shows an exemplary database table 200 for determining a relevanceof items to particular regions of the VU. As shown in FIG. 2, thedatabase table 200 may contain a RelationshipID column 205, anInventoryUUID column 210, a Boundary column 215 and a TimeInBoundarycolumn 220. The RelationshipID column 205 may contain the primary keyfor the records of database table 200. In relational database design, aunique key or primary key is a candidate key to uniquely identify eachrow in a table. A unique key or primary key comprises a single column orset of columns. No two distinct rows in a table can have the same value(or combination of values) in those columns. The InventoryUUID column210 may contain the foreign key to the existing inventory/objects UUIDtable. In the context of relational databases, a foreign key is areferential constraint between two tables. The foreign key identifies acolumn or a set of columns in one (referencing) table that refers to acolumn or set of columns in another (referenced) table. The Boundarycolumn 215 may contain, for example, a region's coordinates (such as anXYZ-XYZ-XYZ convention where every item or asset within thesecoordinates will trigger an association to the region), a landscape nameor coordinates, or a region name or region UUID. Additionally, inembodiments, the data of the Boundary column 215 may start out as aregion, e.g., region UUID, and auto-reduce itself to coordinatesrepresenting a subset of a region based on how an object is moved overtime. The TimeInBoundary column 220 may contain a time measurement thatis incremented as the item remains within the boundary designated in theBoundary column 215.

Additionally, the VU monitoring tool 45 may use, for example, the assetdeletion tool 30, the asset graphical characteristics alteration tool35, and/or the asset archival storage tool 40 to perform an assetreduction. For example, the VU monitoring tool 45 may direct the assetarchival storage tool 40 to move relevant landscape items (andassociated relevant inventory items for that resident) to secondarystorage and delete those items from the region or the user's inventory.

For example, a user may own five islands and six buildings. Inembodiments, the VU monitoring tool 45 may identify areas that have notbeen visited within the predefined time period (and, thus, are notlikely to be visited) by a user. Additionally, the VU monitoring tool 45may identify items associated with the identified areas (e.g., a map ofone of the owned islands that is no longer visited) and the assetarchival storage tool 40 may move the associated items to, for example,a secondary archive, e.g., archival storage system 22C.

In further embodiments, a VU service provider, for example, may utilizethe determined association of items and VU regions (or the relevance ofitems to particular regions of the VU) as an indicator of a change inuser context for the avatar when a particular land or region is visitedand a specific item is withdrawn from inventory. This may enable the VUservice provider to anticipate a need for additional changes orresources without requiring an explicit request from the avatarwithdrawing the item.

2. Reduction by Relevance to Collaboration With Other Residents

In embodiments, the VU monitoring tool 45 may determine whether an itemis relevant or related to collaboration of a VU resident with other VUspecific residents, and whether these residents have had no interactionwithin a predetermined duration. If the resident has not had interactionwithin the predetermined duration, the VU monitoring tool 45 may directan asset reduction of those assets determined to be relevant to the VUcollaboration.

The VU monitoring tool 45 should determine relevance of items tocollaboration with other residents and should associate VU items withresident collaboration. The VU monitoring tool 45 may determine that anitem is relevant or related to collaboration of a resident with otherspecific residents, for example, if the item is only used (e.g., broughtout of inventory or used on land) when the residents are messaging witheach other or in close physical proximity to each other, and is not usedat other times by the specific resident. In embodiments, the VUmonitoring tool 45 may monitor collaboration between residents anddetermine whether a specific resident has collaborated with anotherresident within a predefined time period. If the VU monitoring tool 45determines that the specific resident has not collaborated with theother resident within a predefined time period, the VU monitoring tool45 may determine items deemed to have been relevant during previouscollaborations between the specific resident and the other resident.

FIG. 3 shows an exemplary database table 300 for determining a relevanceof items to particular collaborations between a particular VU residentand other VU residents. As shown in FIG. 3, the database table 300 maycontain an InventoryConversationID column 305, an InventoryUUID column310, an AvatarUUID column 315, a TimeWithAvatar column 320 and aNumberOfReveals column 325. The InventoryConversationID column 305 maycontain the primary key for the records of database table 300. TheInventoryUUID column 310 may contain the foreign key to an existinginventory/objects UUID table. The AvatarUUID column 315 may contain theforeign key to an avatar with whom the particular user is, e.g.,displaying and/or using their object. The TimeWithAvatar column 320 maycontain a time measurement that is incremented as an object remains inthe presence of the avatar identified in the AvatarUUID column 315. TheNumberOfReveals column 325 may contain a numeric that is incrementedevery time the object (identified in the InventoryUUID column 310) wasin the user's inventory, but then brought out in front of the avataridentified in the AvatarUUID column 315. In embodiments, the data of theNumberOfReveals column 325 may indicate more relevance, and thus, forexample, may be weighted higher, than an object the user is alwaysdisplaying, such as a jacket.

Additionally, the VU monitoring tool 45 may direct an asset reductionfor those items deemed relevant to a VU collaboration between a VU userand other VU resident that has not occurred within the predeterminedperiod. For example, the VU monitoring tool 45 may direct the assetarchival storage tool 40 to move relevant collaboration items (andassociated inventory items for that specific resident) to a secondarystorage, e.g., archival storage system 22C and may delete the item(s)from avatar's regions or inventory, e.g., on the storage system 22B.

For example, a user may have had a previous collaboration with anotherresident, during which the user often displayed specific photos and giftart objects from their inventory and put on certain clothing items onlywhen messaging with (or in close physical proximity to) this secondresident. The VU monitoring tool 45 may monitor the frequency of theseinteractions, and may determine that the collaboration has ended.Accordingly, the VU monitoring tool 45 may then direct an itemreduction. For example, the VU monitoring tool 45 may instruct the assetarchival storage tool 40 to move the items deemed relevant to theprevious collaboration to, e.g., the archival storage system 22C anddelete the relevant items from the region or user's inventory.

In further embodiments, a VU service provider, for example, may utilizethe frequency of reveals of a specific item in the presence of anotherspecific avatar or category of avatars to indicate a change in usercontext for the avatar withdrawing the item from inventory. This couldenable, for example, the VU service provider to anticipate the need foradditional changes or resources without requiring an explicit requestfrom the avatar withdrawing the item. This anticipation of needs ischaracteristic of responsive service environments and a servicedifferentiator promoting customer loyalty. For example, if every time anavatar withdraws a briefcase and presentation, the avatar performs apresentation with a particular avatar, the VU service provider could usethe withdrawal of these items from inventory to trigger a request toteleport the two avatars to a presentation hall or to otherwise providea presentation screen.

3. Reduction by Relevance to User Context

With further embodiments, the VU monitoring tool 45 may judge an item tobe relevant or related to a certain user context and the VU monitoringtool 45 may determine whether this context has been invoked within apredetermined duration. If the VU monitoring tool 45 determines that therelevant context has not been invoked within the predetermined duration,the VU monitoring tool 45 may direct an item reduction of the relateditems.

A user context includes a very broad range of attributes that describe auser and which are relevant to their behavioral, search and otherinformational needs. The VU monitoring tool 45 may, in order todetermine relevance of items to user context, associate VU items with aresident's context. For example, the VU monitoring tool 45 may determinethat an item is relevant to or related to a specific user context if theresident only displays this item from inventory or interacts with anitem on the landscape when identified with that user context.

In embodiments, the VU monitoring tool 45 may monitor user context ofthe resident and determine whether the resident's user context haschanged, such that a previous user context is no longer in evidence.While there are potentially a large number potential user contexts forany user population, in embodiments, each user would likely choose, forexample, a single user context or a small number of user contexts thatapply to them in different circumstances. In embodiments, a user mayindicate a new user context, for example, by selecting a new usercontext from a list of user contexts. Additionally, the VU monitoringtool 45 may determine that a previous user context is no longer inevidence if the previous user context has not been invoked for apredetermined time period.

If the VU monitoring tool 45 determines that the resident's user contexthas changed, the VU monitoring tool 45 may determine items deemed tohave been relevant to the previous user context. In embodiments, adatabase may contain For example, as discussed further below, a VUresident may no longer be looking to buy land in the VU and the user'sprevious user context of “land buyer” may no longer be in evidence.Thus, an asset reduction may be performed for assets such as, forexample, previous land sale flyers.

FIG. 4 shows an exemplary database table 400 for determining a relevanceof items to a user context according to a further aspect of theinvention. As shown in FIG. 4, the database table 400 may contain anInventoryContextID column 405, a ContextUUID column 410, anInventoryUUID column 415 and a TimeInContext column 420. TheInventoryContextID column 405 may contain a primary key for the recordsof database table 400. The ContextUUID column 410 may contain a foreignkey to the particular user context stored in a database of potentialuser contexts. The InventoryUUID column 415 may contain a foreign key tothe existing inventory/objects UUID table. The TimeInContext column 420may contain a time measurement or a counter that is incremented as theobject identified in the InventoryUUID column 415 is used in conjunctionwith the user context identified in the ContextUUID column 410.

Additionally, the VU monitoring tool 45 may direct an item reduction ofthose items related to the previous user context. For example, the VUmonitoring tool 45 may direct the asset archival storage tool 40 to movethe relevant inventory items to a secondary inventory or an inventoryarchive, e.g., the archival storage system 22C, and delete thoserelevant inventory items from a region or user's inventory.

For example, a VU resident may no longer be looking to buy land in theVU. Thus, the VU monitoring tool 45 may determine that the user'sprevious user context of “land buyer” is no longer in evidence. One ofthe data points monitored by the VU monitoring tool 45 for contextdetection includes, for example, the observation that the resident is nolonger accepting presence-based advertising flyers for virtual landsales. In embodiments, the VU monitoring tool 45 may determine itemsrelevant to this user context of “land buyer.” For example, the VUmonitoring tool 45 may identify assets such as, for example, previousflyers and/or previously accepted personal gifts associated withpotential land purchases. Additionally, the VU monitoring tool 45 maydirect an item reduction of these identified assets. For example, viathe asset archival storage tool 40, these items may be moved tosecondary storage, e.g., archival storage system 22C, and deleted fromthe resident's personal inventory.

4. Reduction by Relevance to Mode of Transportation

According to further aspects of the invention, the VU monitoring tool 45may determine an item to be relevant or related to a certain mode oftransportation (e.g., walking, teleporting, or flying), and maydetermine that this mode of transportation has not been invoked within apredetermined duration. Accordingly, the VU monitoring tool 45 maydirect an item reduction of those items related to the certain mode oftransportation.

In embodiments, the VU monitoring tool 45 may monitor modes oftransportation of a particular VU resident and determine if the VUresident has used a specific mode of transportation recently, e.g.,within a predetermined time period. If the VU monitoring tool 45determines that a specific mode of transportation has not been usedwithin the predetermined time period, the VU monitoring tool 45 maydetermine items deemed to be relevant to this mode of transportation.

In embodiments, the VU monitoring tool 45 should associate VU items withthe resident's mode of transportation to determine relevance of items tomode of transportation. For example, the VU monitoring tool 45 maydetermine that an item is relevant to a specific mode of transportationif the item is specifically designed to be used with that mode oftransportation.

FIG. 5 shows an exemplary database table 500 for determining a relevanceof items to a particular mode of transportation according to a furtheraspect of the invention. As shown in FIG. 5, the database table 500 maycontain an InventoryTransportID column 505, a TransportUUID column 510,an InventoryUUID column 515 and a TimeWithTransport column 520. TheInventoryTransportID column 505 may contain a primary key for therecords of database table 500. The TransportUUID column 510 may containa foreign key to the particular mode of transportation. TheInventoryUUID column 515 may contain a foreign key to the existinginventory/objects UUID table. The TimeWithTransport column 520 maycontain a time measurement or a counter that is incremented as theobject identified in the InventoryUUID column 515 is used in conjunctionwith the mode of transportation identified in the TransportUUID column510.

According to an aspect of the invention, the VU monitoring tool 45 maydirect a reduction of those items deemed to be relevant to a particularmode of transportation when the VU monitoring tool 45 determines thatthe mode of transportation has not been used for a predetermined timeperiod. For example, the VU monitoring tool 45 may direct the assetarchival storage tool 40 to move the relevant inventory items to asecondary inventory or an inventory archive, e.g., the archival storagesystem 22C, and delete these items from, e.g., the user's inventory orVU landscape.

For example, a user may have an airplane in their personal inventory andmay have placed a landing cue visible from 10,000 feet on their land.The VU monitoring tool 45 may determine whether the user has used theirairplane recently (e.g., within a predetermined time period). If the VUmonitoring tool 45 determines that the VU user has not used the airplanewithin the predetermined time period, the VU monitoring tool 45 maydirect an asset reduction for the landing cue, e.g., the landing cueitem may be removed from the users inventory or the VU landscape, andarchived, e.g., in the archival storage system 22C.

Real World Status Triggers For Asset Reduction

As noted above, the methods described for asset reduction in a VU(permanent or semi-permanent deletion, change in graphicalcharacteristics, temporary reduction via archival storage with optionfor later restoration) may be triggered by a number different criteriawithin the VU. In further embodiments, a change in a real world statusas reported by the user may act as a trigger for asset reduction. Themethods used to determine relevance based on the reported real worldstatus change will vary by embodiment, but all potential methods usedwith the inventive system should have the goal of associating VU itemswith users or the entities for which real world status changes arereported.

In embodiments, a real world status tool 50 may determine a user's realworld status change, by, for example, detecting a change in a user'sprofile or by a user instructing the VU of a real world change via,e.g., a menu based profile. That is, the VU monitoring tool 45 maymonitor changes in real world status profile reported by users, e.g.,via the real world status tool 50, to determine if a user's real worldstatus has changed.

If the VU monitoring tool 45 determines that the user's real worldstatus has changed, the VU monitoring tool 45 may determine items thatare relevant or related to a previous real world status (i.e., the realworld status that has changed) and may direct an item reduction of thoserelated items. For example, the VU monitoring tool 45 may direct theasset graphical characteristics alteration tool 35 to elide graphicaldetails (e.g. coloration) of those items relevant to the previous realworld status.

For example, a VU resident may take a new job with a real world companybut may have forgotten about various VU inventory items they acquiredwhile associated with their previous employer. After the residentreports their real world status change, e.g., via the real world statustool 50, the VU monitoring tool 45 may identify the relevant inventoryitems associated with the former employer (e.g., documents and/oroutfits associated with the former employer) and, for example, maydirect the asset archival storage tool 40 to remove the relevant itemsfrom the VU resident's inventory to an inventory archive, e.g., thearchival storage 22C.

With a further example, a product may not be selling well in anenterprise's physical store and/or their web store. Accordingly, theenterprise's virtual store manager may desire an efficient way to reducethe assets associated with that product in the VU. Thus, in embodiments,the virtual store manager may use the real world status tool 50 toreport each product's real world sales status, e.g., with menu basedprofile. The VU monitoring tool 45 may monitor changes in real worldsales status reported by the virtual store manager via the real worldstatus tool 50. Accordingly, the VU monitoring tool 45 may determinewhether a real world sales status has changed, e.g., indicating reducedsales for specific products via, for example, the real world status tool50. In a further embodiment, the real world status tool 50 may performdata mining of available real world sales data available to authorizedpersonnel, e.g., at the enterprise's web site.

If the VU monitoring tool 45 determines that a real world status haschanged, the VU monitoring tool 45 may determine items deemed to berelevant to these specific products (e.g., virtual flyers and/orpromotional posters linked to the product) and may direct an itemreduction of those relevant items. For example, the VU monitoring tool45 may direct the asset archival storage tool 40 to move the relevantinventory items to a secondary inventory or an inventory archive, e.g.,the archival storage system 22C, and delete these items from the user'sinventory, e.g., in the virtual store. In a further embodiment, the VUmonitoring tool 45 may direct the reduction of inventory assetsassociated with the product, which VU residents have previously taken,e.g., as personal inventory items or assets to be deposited on thelandscape. This embodiment may be particularly relevant in the event ofa recall of a defective product.

Upcoming Event Trigger For Temporary Asset Reduction

In further aspects of the invention, for example, an owner or renter ofspecific land in the VU may be planning a special event on the land,such as, for example, a rock concert or a rally, which may drawadditional VU residents and their inventory to the land. Theseadditional VU residents and their inventory, however, may cause the primobject limit of the land to be exceeded. In order to prevent the primobject limit of the land from being exceeded, for example, the owner ofthe land (or a VU service provider) may initiate temporary personalinventory and asset reduction for all avatars currently on the land, andoptionally, for all avatars who visit the land for the special event.

In embodiments, for example, an organizer of a special event may use thespecial events tool 55 as registration mechanism to indicate a locationfor a special event (e.g., a specific land or region in the VU) and ananticipated number of additional visitors. The VU monitoring tool 45 maymonitor a prim load on the land or region to be used for event.Additionally, the special events tool 55 may estimate the additionalnumber of residents to visit land for the event, e.g., based on reportby the event organizers. Additionally, in embodiments, the specialevents tool 55 may estimate the number of additional VU residents tovisit land for a specific event by a variety of methods, including, forexample, the prior history of similar events and the number ofpre-registrations or ticket purchases (if required) for the upcomingspecial event.

If the VU monitoring tool 45 determines that the prim load for VUresidents currently on the land for the upcoming event plus the primlimit for those residents anticipated to visit the land for the eventapproaches a prim maximum for land, the VU monitoring tool 45 may notifyaffected residents and initiate asset reduction methods, e.g., for theduration of the event. In embodiments, the VU monitoring tool 45 mayidentify categories of assets to be reduced for the duration of thespecial event, using methods which incorporate the prim load associatedwith each asset category as one of the criteria for selecting thiscategory for temporary reduction. Additionally, in embodiments, the VUmonitoring tool 45 may set an individual prim limit for each avatar onthe land, and may direct an asset reduction for those avatars whoseassets exceed the individual prim limits without regard for specificcategories of assets, for example, temporarily reducing an avatar's,e.g., largest assets or least used assets.

Additionally, in embodiments, the VU monitoring tool 45 may optionallydirect, e.g., the deletion or archiving all inventory items associatedwith the special event if those items are left on the land used for thespecial event after the event has concluded. This may include items, forexample, that were created for the special event, items created at thespecial event and/or items used at the special event, amongst otheritems. This constitutes a method for automatic trash removal after aspecific event. The VU monitoring tool 45 may determine relevance ofitems based on their relationship to a just concluded event byassociating VU items with the specific event.

Using the aforementioned criteria and automatic asset reduction methods,VUs will be easier to use by both individuals and corporations.Moreover, the VU infrastructure will be less loaded, giving an advantageto the VU operators and users who make use of this method and system.

Additionally, while the invention has been described using the assetdeletion tool 30, the asset graphical characteristics alteration tool35, the asset archival storage tool 40, the VU monitoring tool 45, thereal world status tool 50 and the special events tool 55, the inventioncontemplates that any of the operations performed by the asset deletiontool 30, the asset graphical characteristics alteration tool 35, theasset archival storage tool 40, the VU monitoring tool 45, the realworld status tool 50 and the special events tool 55 may be performedmanually by a user (e.g., a VU manager, an advertiser or a VU serviceprovider). For example, a VU service provider may alter the graphicalcharacteristics of an asset.

FIG. 6 shows an exemplary flow 600 for performing steps of the inventionusing VU triggers. At step 605, the VU monitoring tool detectsoccurrences of a VU resident's visitation to a region of the VU, acollaboration of a VU resident with another VU resident, a change inuser context of the VU resident or a use of a particular mode oftransportation of the VU resident. At step 610, the VU monitoring tooldetermines whether a subsequent occurrence has taken place within apredetermined time from the preceding occurrence. At step 615, if the VUmonitoring tool determines that a subsequent occurrence has taken placewithin the predetermined time period, the process continues at step 605.At step 615, if the VU monitoring tool determines that a subsequentoccurrence has not taken place within the predetermined time period, theprocess continues at step 620.

At step 620, the VU monitoring tool determines items of the VU residentthat are relevant to the occurrence. At step 625, the VU monitoring tooldirects an asset reduction of those relevant items. For example, the VUmonitoring tool may direct the asset deletion tool to delete therelevant asset from the landscape or the VU resident's inventory, maydirect the asset graphical characteristics alteration tool to elide thegraphical characteristics of the relevant asset, and/or may direct theasset archival storage tool to move the relevant asset to the archivalstorage system.
